Almost nobody's first ten come from content, ads or a funnel. They come from people who already knew the person could do the work: former colleagues, former clients, and the one person who referred three others.
The useful question is therefore not "how do I get leads" but "who already knows what I am good at, and do they know I am available?"
If you are past ten, where did yours actually come from? And if you are at zero, what is stopping you telling the twenty people who already know your work?
